Cert Top 10 Secure Coding Practices

Cybersecurity Career Paths and Certifications In 2024

Cert Top 10 Secure Coding Practices – In today’s world of technology, making sure things are safe is really important. With more and scarier cyber problems happening, it’s super important for people who write code to follow safe ways of doing it. Doing this helps them make sure their computer programs and the people who use them are protected from possible security issues.

This article will talk about ten important ways to write safe code that all programmers should use.

What is Secure Coding?

Secure coding means writing computer programs in a way that keeps them safe from bad people who might try to break into them or cause problems. It’s like building a strong fortress for your software so that no one can easily sneak in and cause trouble. This involves following certain rules and practices to make sure your code is strong and protected against attacks or vulnerabilities.

Cert Top 10 Secure Coding Practices To Stop Cyber Attacks

  1. Input Validation: The initial safeguard in fortifying an application involves input validation. Through the careful assessment and purification of user inputs, developers can thwart prevalent attacks such as SQL injections and cross-site scripting (XSS). Diligently filtering and validating user input serves as a deterrent against the execution of malicious code and unauthorized access to sensitive data.
  2. Robust Authentication Measures: The implementation of resilient authentication mechanisms holds paramount importance in shielding user accounts. Developers must employ rigorous password guidelines, enforce encryption of passwords, and integrate multi-factor authentication (MFA) wherever feasible. Additionally, prudent strategies such as limiting login attempts and instituting account lockouts are advisable to deter brute force attacks.
  3. Ensuring Secure Session Management: The meticulous management of user sessions stands as a pivotal aspect in guaranteeing their security. Developers should employ secure session tokens, institute session expiration protocols, and refresh session IDs upon user verification. These measures act as deterrents against session hijacking and fixation attacks.
  4. Effective Error and Exception Handling: Prudent management of errors is integral to averting potential security vulnerabilities. Here Developers are tasked with ensuring that error messages refrain from disclosing sensitive information that could be exploited by malicious actors. Instead, offering generalized error messages to users while maintaining comprehensive logs for diagnostic purposes is advisable.
  5. Safeguarding Data Storage: To shield sensitive data, developers must adopt encryption for data at rest. The adoption of robust encryption algorithms coupled with secure key management practices is pivotal. Additionally, sensitive data should never be stored in plaintext or hardcoded within the application’s source code.
  6. Security in Data Transmission: Given that applications frequently transmit data across networks, this data becomes susceptible to interception. Developers should prioritize the use of secure communication protocols such as HTTPS and SSL/TLS to encrypt data during transmission, ensuring both data confidentiality and integrity. Moreover, the practice of abstaining from transmitting sensitive information through URL parameters or HTTP GET requests is prudent.
  7. Principle of Least Privilege: Adhering to the principle of least privilege is imperative to confine each user or component within the system to only the necessary resources. Developers are tasked with limiting access rights and establishing appropriate access controls to curtail the potential fallout from compromised accounts.
  8. Regular Updates and Patching: The continuous maintenance of both the application and its dependencies holds pivotal significance for security. Developers should consistently update frameworks, libraries, and platforms to address known vulnerabilities. Remaining vigilant about emerging security threats and promptly applying required patches is equally crucial.
  9. Adhering to Secure Coding Standards: Following secure coding standards empowers developers to produce more resilient code. Abiding by established coding practices, such as steering clear of insecure functions, averting buffer overflows, and managing memory prudently, is instrumental in diminishing the susceptibility to security loopholes.
  10. Ongoing Testing and Code Review: Routine code testing and comprehensive reviews are essential to pinpoint and rectify security weaknesses. The incorporation of static code analysis tools and the execution of thorough security evaluations throughout the development process significantly enhance the overall security posture of an application.

Benefits Of Secure Coding Practices

Using secure coding methods brings many good things such as avoiding cyber attacks, malicious softwares etc. I have listed some more below;

  1. Strong Protection: It keeps your software safe from bad people who might try to break in.
  2. People Trust: When you make sure their information is safe, users feel good using your stuff.
  3. Saves Money: Fixing problems early costs less than fixing them after a bad thing happens.
  4. Good Reputation: People think highly of you when you show you care about their safety.
  5. Following Rules: It helps you do what the rules say about keeping data safe.
  6. Less Time Offline: Secure code means fewer chances for big problems, so your stuff stays working.
  7. Works for a Long Time: Secure code helps your software last and not have big problems later.
  8. Easier to Work Together: Developers can work better when they trust the code is good and safe.
  9. More Ideas: When you don’t worry too much about security, you can think of new and better things for your software.

Note: Secure coding isn’t just about stopping cyber attacks,  it makes your software better and helps people trust and like what you make.


Using secure coding methods is really important in today’s digital safety world. By doing things like checking information from users, making strong ways for people to log in, keeping user sessions safe, handling mistakes carefully, storing data in a strong way, sending data in a secret code, giving limited access to things, keeping everything up to date, following safe coding rules, and checking code often, programmers can build a strong shield to protect their programs from possible dangers.
